5 Clai S (01. 45-24) This invention relates to improvements in the.

embroidery art and has particular reference to a frame used especially to hold small articles, such as handkerchiefs and the like, while being embroidered with various ornamental designs. v

- With frames of this character, it-has heretofore been the custom to provide the clamping bars with a covering of elastic material which is vul- 10 canized onto the bars so as to firmly adhere thereto and whichis' designed to protect a fabric against abrasion or tearing when heldin the frame. It has been found in practice'that the gripping effect of the elastic covering, which is made of rubber, takes place on the sides of the bar and that with the finer quality of silk fabrics thisgrippingaction has frequently caused a tearing of the fabric. Also, it has been noted that the rubber, covering becomes sticky in high temperatures, causing'the fabric to adhere to the rubber. Because of this ithas been' sometimes necessary to discard the frames muse and replace them with others; thus making the use of such frames a comparativelyexpensiveproposition.

An object of the present invention is to simplify the construction of frames of the above charac ter andf'thereby reduce cost of manufacture 30 thereof, by utilizing a protective strip, preferably made of elastic-material such as rubber, which is introduced into each channel bar of the frame vand frictionally held therein by, contact withthe walls of said bar so that said strip may be readily removed and replaced when the same becomes ineffective to properly grip the fabric between the channel and clamping bars of the frame. h I

Another object is to securely clamp a fabric to one end of the frame by the provision of an i'm-r proved form of clamping member which grips the fabric in such manner as to hold the gripped 'portion in the same plane with those portions which engage over the edges of the channel bars. The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawing which illustrates preferred embodiments of the inventive idea.

In the drawing: s, Figure 1 is a fragmentary plan view of th embroidery frame constructed in accordance with the invention. p I Figure 2 is a longitudinal section on the line .22 of Figure 1. v

Figure 3 is a similar section on -the-1ine 33 ofFigurel; I j Figure i'isa transverse section taken through one of the channel bars showing a protective strip therein, inits normal position.

Figure 5 is a transverse section illustrating the manner in which a fabric is clampedj'within one of the channel bars and between the'protective strip and a clamping bar. a Figure 6 is an enlarged longitudinalsection through one of the channel bars showing the pro tective strip and clamping bar in association therewith, and I Figure '7 is a plan view of a slightlymodified form of clamping member such' as illustrated in Figure3. f i j f" Referring more particularly to the accompanying drawing, the numerals 10 and'11 illustrate two end frame pieces which'are-interconnected by a series of channel bars 12," preferably of U-shape in cross section having their ends recessed within' the members '10 and 11 so that the free outer edges of said bars will be; substantially-flush with the outer surfaces o'f'said members. The channel bars are arranged in pairs, an as shown inFigure 1,wit heach bar of 'a'pai'r disposed contiguous, to a bar of the next adjacent pair. The endof each bar 12 which-is disposed in the end member 11 has its channel constricted as indicated at 13 and'within this portion of the channel there is pivoted at 14 one end of a clamping bar '15 which is slightly bowed longitudinally, I as indicated in Figure 2, when thebar "is in its normal or'inoperative position. The other ex tremity .of the bar 15 is twisted at right angles 901 to form a grippin'g portion 16 andwhen'thefree extremity of said bar is depressed in the' 'act of gripping an edge of a fabric within the channel bar, said clampingbar will flexsuflicientlyso that it will be positioned entirely within the 'confines of the channel of'the b'ar '12 after which a rotative latch 17 carried by the end piece 11 may be turnedrto extend over the channel of the bar 12 and contact the outer edge of the bar 15 so as to prevent the latter from springing out of the channel. n

In accordance with the present inventions. protective means is provided for engagement by a fabric being clamped so that the fabric will come in contactwith as little of the metalof the co- 0 operating bars as possible and thus'be protected against abrasion 'or possible tearing. when the fabric is clamped in its tautened position in the 7 frame. 'As distinguished from prior' usage, in whichthis protective element has been-vulcan- PA; NT [OFFICE 'a diameter slightly greater than the width of the channel in said'bar so that when the strip is inserted it will frictionally engage the side walls 7 of the bar and thus be retained in position until such time when it is desired to remove the same for replacement purposes. At such times, theextraction of the strip or tubing from the channel bar may be expeditiously. accomplished, thus providing a distinct improvement over the previously described device which has been used heretofore and which necessitates the discardingof the entire frame when the protective strips thereof have lost their eificiency.

' After a portion of a fabric 19 to be clamped has been laid across one of the channel bars 12 with-a strip 18 therein, the associated clamping bar 15 is brought down upon the said portion of the fabric with the inner edge of said bar f0rcing the fabric into contact with the strip 18, thus slightly compressing the latter as shown in Fig ure 5. With the fabric thus gripped between the inner edge of the bar 15 and the strip 18, and not against the side walls of the channel bar 12,

there is a great deal less tendency for the gripping elements to tear or otherwise injure the fabric especially when finer'quality of silks are used. When the clamping operation is completed and the bar 15 is entirely recessed within the channel in its associated bar 12, an adjacent latch 1'7 is rotated to engage the outer edge of the bar 15 and thus retain it in its operative position.-

- It is also desirable to clamp or grip the fabric to be embroidered at the end or portion thereof adjacent the end piece 10 and between the channel bars of each pair. -To this end, the present invention contemplates the provision of a clamping member comprising a pair of pivotally connected and spring-pressed gripping jaws 20 and 21 the former of which has one end secured at 22 to the inner edge of the end piece 10 while the adjacent end 23 of the jaw 21 extends over the outer face of the piece 10 in alignment with the recess 24 therein, said recess enabling the end 23 to be depressed so as to spread apart the gripping ends of said piece preparatory to inserting a portion of the fabric 19 therebetween. The jaws 20. and 21 areprovided with inturned and overlapping gripping flanges or portions 25 and 26, respectively, which are so positioned relative to I each other as to securely clamp the fabric therebetween. In order that the fabric may have a smooth unbroken surface within the confines of the edges and ends thereof that are held by the bars 12 and 15 and the clamping members, the

free edge of the portion 25 of the jaw 20 of the clamping member is in the same plane with the outer or free edges of the channel bars, and clearly indicated in Figure 3.

In Figure 1, there is shown a single clamping member disposed between the bars 12 of each pair, but where the space between said bars may be larger to accommodate a piece of fabric of greater width a clamping device such as shown in'Figure '7 may be employed. In this modification, two clamping members, generally indicated by the numeral 27 and each constructed in the same manner as the similar clamping member above described, have the upper or outer clamping jaws interconnected by a strap or a yoke 28 so that when pressure is exerted upon either of the jaws or the strap the same will move into the recess 29 formed in the end piece 10 and the gripping ends of both clamping members 27 will be spread apart to receive the fabric therebetween What'is claimed is: a v 1.
